Harness the power of the Mammoth

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'10"
    Weight: 165 lbs
    Size Purchased: Large

OG fade on the color - awesome fitting, stretchy, comfy - lovin it!


Very nice!!

  • Familiarity:I've put it through the wringer
  • Fit:Runs small
  • Height: 5'11"
    Weight: 190 lbs
    Size Purchased: XL

I love Mammut clothing and this shirt is another good choice. It's really quite soft. The neck stretches out a little larger than I like but I still love it. I'm 5'11 and 190 with a pretty athletic build. I opted for the XL for the roominess and I was quite happy the size fits great.


Nice Product, Much Shrinkage

  • Fit:Runs small

Shirt fabric and printing are very nice, but be mindful of shrinkage. I am a medium with all t-shirts I wear, so I ordered medium. When I received the shirt it looked small for a medium, I returned it and it was replaced with a large. When I received the large, it too looked smaller than usual, I tried it on and I was worried that it might be too small after washing, so I washed it in cold water and dried at low temp...too small.


Heavy Duty

  • Familiarity:I've used it once or twice and have initial impressions

It is definitely a nice shirt, well made.


Thick and thin

    Great quality material and attention to detail on seams and appearance. Runs a little narrow; good if you're thin. Have a feeling it will be with me for a while.


    Size up, but great shirt.

      Nice thick material used, but I got an xl as I usually do in most shirts and it was pretty tight in the chest. If you're a skinny guy (or girl) who usually goes with a large I would think about sizing up. Sizing up will give you a bit extra length but about a size up seems to be the way to go on this one. Great buy otherwise, great durably materials but I wouldn't count on it if you are looking for a light shirt that will be good in heat, pretty thick.
